How can I make sure I bid and win on eBay?

There's an item on eBay I really need to get. There's no bids on it yet and the auction ends in 4 days

The problem is it runs out at stupid o clock in the morning! 5 to 4am 4 days from now, I won't be up to see if I win itcos I'll be in bed asleep!

What should I do?
Update: Someone has put a bid in 2 hours ago now wtf do I do
